Good for Mika Brzezinski!
What the video doesn’t make clear is that this is three different incidents, each taking place an hour apart; Brzezinski reads the news at 7am, 8am and 9am, and each time the producer handed her a script with Paris Hilton as the lead story. Each time she refused to read it; the first time simply refusing (the male co-hosts goading her on), the second time trying to set the script on fire (the male host physically grabbed the script from her hands), and the third time theatrically shredding the script.
Kinda a shame that the co-hosts (or whatever) on the program marred her protest by acting like sexist, condescending buffoons throughout.
Check out this interview with Brzezinski about the incident (apparently she’s gotten overwhelmingly positive reactions). And a thematically related Youtube Link, in which MSNBC makes it crystal clear what they think the real news of the day is.
